(1) These power ratings and currents are for a maximum ambient temperature of 50°C and a switching frequency of 4 kHz in continuous operation.The switching frequency is adjustable from 2 to 16 kHz. Above 4 kHz, the drive will reduce the switching frequency in the event of excessive temperature rise. The temperature rise is controlled by a sensor in the power module. Nonetheless, the nominal drive current should be derated if operation above 4 kHz needs to be continuous. Derating curves are shown on page 15 as a function of switching frequency, ambient temperature and mounting conditions. (2) Current on a line supply with the "Max. prospective line Isc" indicated. (3) Peak current on power-up, for the max. voltage (240 V + 10%). (4) For 60 seconds. (5) These references can be ordered without terminal board in order to integrate an optionnal communication board. Add a B at the end of the reference. For example, ATV312HU11M2 becomes ATV312HU11M2B.

Bus voltage measurement procedure
DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Read and understand the precautions in “Before you begin” page 5 before performing this procedure. Failure to follow these instructions will result in death or serious injury. The DC bus voltage can exceed 933 Vdc. Use a properly rated voltage-sensing device when performing this procedure. To measure the DC bus voltage: 1. Disconnect all power. 2. Wait 15 minutes to allow the DC bus to discharge. 3. Measure the voltage of the DC bus between the PA/+ and PC/– terminals to ensure that the voltage is less than 42 Vdc. 4. If the DC bus capacitors do not discharge completely, contact your local Schneider Electric representative. Do not repair or operate the drive.

Wiring
Recommendations Power and circuit protection The drive must be grounded to conform with the regulations concerning high leakage currents (over 3.5 mA). Where local and national codes require upstream protection by means of a residual current device, use a type A device for single-phase drives and a type B device for three-phase drives as defined in the IEC Standard 60755. Choose a suitable model integrating: • High frequency current filtering, • A time delay that helps to prevent tripping caused by the load from stray capacitance on power-up. The time delay is not possible for 30 mA devices; in this case, choose devices with immunity against nuisance tripping. If the installation includes several drives, provide one "residual current device" per drive. Keep the power cables separate from circuits in the installation with low-level signals (detectors, PLCs, measuring apparatus, video, telephone). If you are using cables longer than 50 m (164 ft) between the drive and the motor, add output filters (please refer to the catalogue).
Control Keep the control circuits away from the power cables. For control and speed reference circuits, we recommend using shielded twisted cables with a pitch of between 25 and 50 mm (1 and 2 in.), connecting the shielding to ground at each end.
Equipment Grounding Ground the drive according to local and national code requirements. A minimum wire size of 10 mm² (6 AWG) may be required to meet standards limiting leakage current.
DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH • The drive panel must be properly grounded before power is applied. • Use the provided ground connecting point as shown in the figure below. Failure to follow these instructions will result in death or serious injury. • Ensure that the resistance of the ground is one ohm or less. • When grounding several drives, you must connect each one directly, as shown in the figure to the left. • Do not loop the ground cables or connect them in series.
WARNING IMPROPER WIRING PRACTICES • The ATV312 drive will be damaged if input line voltage is applied to the output terminals (U/T1,V/T2,W/T3). • Check the power connections before energizing the ATV312 drive. • If replacing another drive, verify that all wiring connections to the ATV312 drive comply with wiring instructions in this manual page 29. Failure to follow these instructions can result in death, serious injury, or equipment damage.
WARNING INADEQUATE OVERCURRENT PROTECTION • Overcurrent protective devices must be properly coordinated. • The Canadian Electrical Code and the National Electrical Code require branch circuit protection. Use the fuses recommended in the installation manual. • Do not connect the drive to a power feeder whose short-circuit capacity exceeds the drive short-circuit current rating listed in this manual page 29. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Wiring (continued)
Electromagnetic compatibility (EMC) IMPORTANT: The high frequency equipotential ground connection between the drive, motor, and cable shielding does not eliminate the need to connect the ground (PE) conductors (green-yellow) to the appropriate terminals on each unit.
Principle and precautions • Grounds between the drive, motor, and cable shielding must have high frequency equipotentiality. • When using shielded cable for the motor, use a 4-conductor cable so that one wire will be the ground connection between the motor and the drive. Size of the ground conductor must be selected in compliance with local and national codes. The shield can then be grounded at both ends. Metal ducting or conduit can be used for part or all of the shielding length, provided there is no break in continuity. • When using shielded cable for Dynamic Brake (DB) resistors, use a 3-conductor cable so that one wire will be the ground connection between the DB resistor assembly and the drive. The size of the ground conductor must be selected in compliance with local and national codes. The shield can then be grounded at both ends. Metal ducting or conduit can be used for part or all of the shielding length, provided there is no break in continuity. • When using shielded cable for control signals, if the cable is connecting equipment that is close together and the grounds are bonded together, then both ends of the shield can be grounded. If the cable is connected to equipment that may have a different ground potential, then ground the shield at one end only to prevent large currents from flowing in the shield. The shield on the ungrounded end may be tied to ground with a capacitor (for example: 10 nF, 100 V or higher) in order to provide a path for the higher frequency noise. Keep the control circuits away from the power circuits. For control and speed reference circuits, we recommend using shielded twisted cables with a pitch of between 25 and 50 mm (1 and 2 in.) Keep the control circuits away from the power circuits. For control and speed reference circuits, we recommend using shielded twisted cables with a pitch of between 25 and 50 mm (1 and 2 in.) • Ensure maximum separation between the power supply cable (line supply) and the motor cable. • The motor cables must be at least 0.5 m (20 in.) long. • Do not use surge arresters or power factor correction capacitors on the variable speed drive output. • If using an additional input filter, it should be mounted as closed as possible to the drive and connected directly to the line supply via an unshielded cable. Link 1 on the drive is via the filter output cable. • For installation of the optional EMC plate and instructions for meeting IEC 61800-3 standard, refer to the section entitled “Installing the EMC plates” and the instructions provided with the EMC plates.
DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH • Do not expose cable shielding except where connected to ground at the metal cable glands and underneath the grounding clamps. • Ensure that there is no risk of the shielding coming into contact with live components. Failure to follow these instructions will result in death or serious injury.

EMC plate supplied with the drive, to be installed as indicated on the diagram. Altivar 312 Non-shielded power supply wires or cable Non-shielded wires for relay contacts Attach and ground the shielding of cables 6, 7 and 8 as close as possible to the drive: - Strip the shielding. - Use stainless steel cable clamps of an appropriate size on the parts from which the shielding has been stripped, to attach them to the plate 1. The shielding must be clamped tightly to the metal plate to improve electrical contact. 6. Shielded cable for motor connection with shielding connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes. For 0.18 to 1.5 kW drives, if the switching frequency is higher than 12 kHz, use cables with low linear capacitance: max. 130 pF (picoFarads) per meter. 7. Shielded cable for connecting the control/signalling wiring. For applications requiring several conductors, use cables with a small cross-section (0.5 mm2, 20 AWG). The shielding must be connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes. 8. Shielded cable for connecting braking resistor (if used). The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes. Note: • If using an additional input filter, it should be mounted under the drive and connected directly to the line supply via an unshielded cable. Link 3 on the drive is then via the filter output cable. • The HF equipotential ground connection between the drive, motor and cable shielding does not remove the need to connect the PE ground conductors (green-yellow) to the appropriate terminals on each unit.

Wiring (continued)
Operation on an IT system IT system: Isolated or impedance earthed neutral. ATV312ppppM2 and ATV312ppppN4 drives have a built-in EMC filter. As a result they exhibit leakage current to ground. If the leakage current creates compatibility problems with your installation (residual current device or other), then you can reduce the leakage current by opening the IT jumper. In this configuration EMC compliance is not guaranteed. Use a permanent insulation monitor compatible with non-linear loads (for example Merlin Gerin type XM200).

Check list
Read carefully the safety information in programming, installation, simplified manuals and the catalogue. Before starting up the drive, please check the following points regarding mechanical and electrical installations, then use and run the drive. For complete documentation, refer to www.schneider-electric.com.
1. Mechanical installation • For drive mounting types and recommendations on the ambient temperature (see the Mounting instructions on page 14). • Mount the drive vertically as specified (see the Mounting instructions on page 14). • The use of the drive must be in agreement with the environments defined by the standard 60721-3-3 and according to the levels defined in the catalogue. • Mount the options required for your application (see catalogue).
2. Electrical installation • Connect the drive to the ground (see Equipment Grounding on page 17). • Ensure that the input power voltage corresponds to the drive nominal voltage and connect the line supply as shown on the drawing on page 18. • Ensure to use appropriate input power fuses and circuit breaker. • Wire the control terminals as required (see Control terminals on page 24). Separate the power cable and the control cable according to EMC compatibility rules. • The range ATV312ppppM2 and ATV312ppppN4 integrates EMC filter. The leakage current can be reduced using the IT jumper as explained in the paragraph Operating on an IT system on page 28. • Ensure that motor connections correspond to the voltage (star, delta).
3. Use and run the drive (see programming manual) • Start the drive and you will see [Standard mot. freq] (bFr) at the first power on. Check that the frequency defined by the frequency bFr (the factory setting is 50 Hz) is in accordance with the frequency of the motor. • On first power-up parameters [Ref.1 channel] (Fr1) and [2/3 wire control] (tCC) appear after bFr. These parameters should be set if you want to control the drive locally, see page «How to control the drive locally» in the programming manual. • On subsequent power-up, rdY will be displayed on the HMI. • The [Restore config.] (FCS) function, permits you to reset the drive with factory settings.

Maintenance
Servicing The Altivar 312 does not require any preventive maintenance. However, it is advisable to perform the following checks regularly: • The condition and tightness of connections. • Ensure that the temperature around the unit remains at an acceptable level and that ventilation is effective. Average service life of fans: 10 years. • Remove any dust from the drive. • Ensure proper fan operation. • Physical damage to covers.
Assistance with maintenance, detected fault display If a problem arises during setup or operation, ensure that the recommendations relating to the environment, mounting and connections have been observed. The first fault detected is stored and displayed, flashing, on the screen: the drive locks and the status relay (R1) contact opens.
Clearing the detected fault Disconnect the drive power supply in the event of a non-resettable fault. Wait for the display to go off completely. Find the cause of the detected fault and correct it. Restore power to the drive. The detected fault will no longer be present if it's cause has been corrected. In the event of a non resettable detected fault: - Remove/cut the power to the drive. - WAIT 15 MINUTES to allow the DC bus capacitors to discharge. Then follow the “Bus Voltage Measurement Procedure” page 16 to verify that the DC voltage is less than 42 V. The drive LEDs are not indicators of the absence of DC bus voltage. - Find and correct the detected fault. - Restore power to the drive to confirm the detected fault has been rectified. Certain detected faults can be programmed for automatic restart after the cause has disappeared. These detected faults can also be reset by cycling power to the drive or by means of a logic input or control bit.
Display menu Use the display menu to show the status of the drive and it's current values as an aid for finding the causes of detected faults.
Spares and repairs Serviceable product: replacement of spares following the catalog.
Procedure after a long time storage
WARNING RISK OF EXPLOSION AT THE POWER UP The capacitors after a long time storage can have issues. Following a storage time between 2 and 3 years: • Use one AC supply variable connected between L1, L2 and L3 • Increase AC supply voltage to have: - 25% of rated voltage during 30mn - 50% of rated voltage during 30mn - 75% of rated voltage during 30mn - 100% of rated voltage during 30mn Failure to follow these instructions can result in death, serious injury, or equipment damage.
